DALLAS (CBSDFW) — Dallas Mavs owner Mark Cuban pulled no punches as he went on a brutal twitter rant Thursday night slamming Donald Trump as he accepted the GOP’s presidential nomination at the Republican National Convention.

Launching a volley of tweets Thursday evening, the Dallas billionaire mocked Trump’s presentation and rhetorical style and let the people of the world know that Americans were “nothing like” Donald.

Dear world. Please ignore what the loud guy in the suit is saying. Americans are nothing like him. We love our country and are proud of it
